Title: Method for non-invasive measurement of an analyte
Inventor: CHAIKEN JOSEPH
IPC: A61B5/145
Filed: 1998-11-12
Abstract: Disclosed is a method and apparatus for mea-suring an analyte in a tissue of a subject. The method comprises contacting the tissue with elec-tromagnetic radiation having a first excitation wave-length, wherein the first excitation wavelength is substantially equal to an absorption wavelength of a temperature probe within the tissue. The tempera-ture probe and the analyte are sufficiently proximate to one another that energy deposited into one by ab-sorption of radiation is transferred to the other. The Raman spectra emitted by the tissue are collected and analyzed to determine a concentration of ana-lyte present in the tissue. The analysis can com-prise measuring the Raman spectra associated with the temperature probe. In addition, the method can include simultaneously contacting the tissue with electromagnetic radiation having the first excitation wavelength and with electromagnetic radiation hav-ing a second excitation wavelength, wherein the second excitation wavelength is substantially equal to an absorption wavelength of the analyte. The analysis comprises comparing the spectra emitted in response to the first excitation wavelength in the presence and in the absence of the second excita-tion wavelength. In another embodiment, the analy-sis comprises measuring the anti-Stokes component of the Raman spectra associated with the analyte.  The method provides a non-invasive measurement of blood glucose, using hemoglobin as the temper-ature probe.

Title: Digital demodulator
Inventor: KATOH HISAKAZU
IPC: H04L27/233
Filed: 1998-12-25
Abstract: A digital demodulator that eliminates the need for a device for generating absolute phase. In a digital demodulator for a digital broadcast receiver that receives digital time-division multiplexed signals of different types of modulation, the demodulated baseband signal is selectively inverted by an inverter (7) according to an inversion command signal "0" or "1" that is output from an inversion decision circuit (6) depending on a BPSK signal of a known pattern. A phase error detector (8) for carrier reproduction determines the phase error voltage based on the phase difference between the absolute phase and the phase of the signal point of the demodulated baseband signal output from the inverter (7). The phase error voltage is passed through a carrier filter (9), including a low-pass filter, to control the carrier frequency so that carrier reproduction can be carried out with the phase at the signal point being coincident with the point of phase convergence.

Title: Methods of making stators for moineau pumps
Inventor: WALTERSKOETTER MARKUS
IPC: B21C37/20
Filed: 1998-12-17
Abstract: The present invention provides methods of forming mud motors. In one method, rollers are urgingly stroked against a tubular member having a mandrel therein that has an outer profile which is the inverse of the desired profile of the stator. In another method, rollers are urged and rotated radially on the tubular member with the mandrel disposed in the tubular member. In yet another method, dies are pressed against the tubular member having a mandrel with a desired outer profile. In another method, a molten metal is deposited over a mandrel with an outer lobed surface that is substantially the inverse of the desired inner profile of the stator housing. The mandrel is then removed, leaving a metallic longitudinal member having an inner profile defined by the outer profile of the mandrel. The mandrel may also be a preformed liner of desired thickness having an inner and outer lobed surface.  In each of these methods, the inner surface of the resulting member has the profile defined by the outer profile of the mandrel. The inner surface of the resulting member then may be coated or lined with a suitable material such as an elastomer or a ceramic. The stator inner surface may also be metallic. A suitable rotor is then disposed in the stator to form the drilling motor.
